Antenna designs for hearing instruments
An antenna for a hearing instrument is connected to a first feedline segment extending laterally along an inner posterior surface of a shell of the hearing instrument. The antenna is also connected to a second feedline segment extending laterally along the inner posterior surface of the shell. The antenna comprises a first arm connected to the first feedline segment. The first arm initially extends in an inferior direction along the inner posterior surface of the shell from the first feedline segment. A second arm is connected to the second feedline segment and initially extends in a superior direction along the inner lateral surface of the shell from the second feedline segment.
1. An antenna for a hearing instrument, wherein the antenna is connected to:
a first feedline segment extending laterally along a first inner lateral surface of a shell of the hearing instrument, and
a second feedline segment extending laterally along the first inner lateral surface of the shell of the hearing instrument, and
wherein the antenna comprises:
a first arm connected to the first feedline segment and initially extending in an inferior direction, along the first inner lateral surface of the shell, from the first feedline segment; and
a second arm connected to the second feedline segment, wherein:
the second arm includes a first lateral segment, a superior segment, and a second lateral segment,
the first lateral segment extends in a superior direction along the first inner lateral surface of the shell from the second feedline segment,
the superior segment extends in a sagittal direction along an inner superior surface of the shell, and
the second lateral segment extends in the inferior direction along a second inner lateral surface of the shell.
2. The antenna of claim 1 , wherein a width of the second lateral segment is greater in a superior portion of the second lateral segment than an inferior portion of the second lateral segment.
3. The antenna of claim 2 , wherein the second arm further includes an inferior segment that is connected to an inferior end of the second lateral segment and extends in the sagittal direction.
4. The antenna of claim 1 , wherein the antenna is configured to operate in accordance with a Bluetooth™ Low Energy standard.
5. A method of manufacturing a hearing instrument, the method comprising:
connecting a first terminal to a first feedline segment extending laterally along a first inner lateral surface of a shell of the hearing instrument, and
connecting a second terminal to a second feedline segment extending laterally along the first inner lateral surface of the shell of the hearing instrument, and
wherein an antenna comprises:
a first arm connected to the first feedline segment and initially extending in an inferior direction, along the inner lateral surface of the shell, from the first feedline segment; and
a second arm connected to the second feedline segment, wherein:
the second arm includes a first lateral segment, a superior segment, and a second lateral segment,
the first lateral segment extends in a superior direction along the first inner lateral surface of the shell from the second feedline segment,
the superior segment extends in a sagittal direction along an inner superior surface of the shell, and
the second lateral segment extends in the inferior direction along a second inner lateral surface of the shell.
6. The method of claim 5 , wherein a width of the second lateral segment is greater in a superior portion of the second lateral segment than an inferior portion of the second lateral segment.
7. The method of claim 6 , wherein the second arm further includes an inferior segment that is connected to an inferior end of the second lateral segment and extends in the sagittal direction.
8. The method of claim 5 , wherein the antenna is configured to operate in accordance with a Bluetooth™ Low Energy standard.
